GLOSSARY

Flatulence concerns intestinal gas and its passage, not always tracking bloating sensation or abdominal distension.

Bloating, nausea and bowel changes have multiple causes; one meal does not establish a disease or enzyme deficiency. Record foods, amounts, timing, exercise and medicines. Severe or persistent pain, bleeding, repeated vomiting or unintended weight loss warrants assessment. Digestive discomfort should not automatically trigger enzyme supplements or unsupervised exclusion of an entire food group, especially when the athlete already struggles to meet energy needs.

Exercise intensity, heat, mechanical movement, splanchnic blood flow and fueling choices can influence gut symptoms. Gradually practicing eating and drinking helps characterize and sometimes improve tolerance. Severe symptoms are not a training target. Repeated discomfort requires review of multiple factors rather than automatically blaming gluten, lactose or one transporter. An individualized plan should support both fuel delivery and comfort without unnecessary restriction of the wider diet.

For sports use, consider meal size and timing together with fluids, intensity and composition. Large, fiber-rich or fatty meals close to exercise trouble some individuals, but tolerance varies. Changing one factor during training and recording responses helps identify patterns. First-time competition products or broad food exclusions without a replacement plan do not substitute for this practical evaluation and can compromise adequate fueling.
